Open Question: Test Drive Unlimited ( TDU ) problem.?

Ok I wanna start by saying that I dont have the game registered and I dident buy it so I cant register, just leave it that way. Anyway after I install the Megapack or just the 1.66a patch the game works but I cant race and/or use the GPS. When I enter a race and after I press START nothing happens, all I can see is the pre-race screen. As for the GPS when I press M (default key) the game crashes. I tryed reinstalling the game/megapack/patch and the same thing happens every time :( PS: I play offline :)
